文摘
In the present work, a numerical study is considered to predict the transport phenomena during solidification of a transparent binary solution (NH4Cl?+?H2O) on an inclined cooling plate. During solidification, a shear layer is developed near the mush. The present work involves the prediction of the transport phenomena during solidification of the binary solution under this shear flow. In the mathematical model of this solidification process, the free surface of the solution is traced by the volume-of-fluid method and the solidification phenomenon is represented by a set of volume averaged single phase mass, momentum, energy and species conservation equations. The governing equations are solved based on the pressure-based finite volume method according to the SIMPLER algorithm using TDMA solver along with the enthalpy update scheme. Finally, the simulation predicts the temperature, velocity, solid fraction and the species distributions in the computational domain.
